Abstract

Six-membered, nitrogen-containing, heterocyclic, aromatic compounds of the general formula <FORM:1059231/C2/1> where x is 3, 4 or 5, Y is chlorine or fluorine and at least one of the atoms represented by Y is fluorine, are prepared by heating the corresponding nitrogen-containing heterocyclic aromatic compound with chlorine atoms attached to the carbon atoms in the aromatic ring with a dry alkali metal fluoride at 350 DEG to 600 DEG C. for 1 minute to 24 hours. Reference has been directed by the Comptroller to Specification 914,933.
